论文摘要
Belle合作的相关生产的数据（带有光脱光的强子）和单个横向极化的$λ$ - hyperons的单一包含在$ e^+e^ - $ $ nihihilation过程中，首次在TMD方法中提取的过程，首次$λ$偏光片段化功能。在$ e^+e^ - $ nihilation过程中，在软性共线有效理论方法中，在$ e^+e^ - $ nihiHIHIHATION过程中计算跨部分的最新理论发展，并将其与CSS形式主义结合在一起，可用于双重 - hadron生产案例，可用于执行重新分析，采用完整的TMD因素化方案。提出了两个分析之间的初步结果和比较。
Data from the Belle Collaboration for associated production (with a light unpolarized hadron) and single-inclusive production of transversely polarized $Λ$-hyperons in $e^+e^-$ annihilation processes allowed to extract within a TMD approach, for the first time, the $Λ$ polarizing fragmentation function. Recent theoretical developments on the computation of cross sections for single-inclusive hadron production in $e^+e^-$ annihilation processes, within a Soft Collinear Effective Theory approach, combined with the CSS formalism for the double-hadron production case, can be used to perform a renewed analysis, adopting a full TMD factorization scheme. Preliminary results and a comparison between the two analyses are presented.
